After the aesthetic move 1...Bc2!, the white king is forced to neglect the protection of his rook, for the capture of the bishop with the rook fails to Ra3#.

After 1...Bc2! 2.Kc2: Ra2:+ 3.Kd1 Ne3+ white has not only lost material; he will also find himself in a mating net build by black's rook, knight and king, soon.
